# Script allows to change machine and instance identifiers, it leads to the following changes on agent:
# - DML database will be cleared
# - Archives database will be cleared
# - Certificates for Online Backup will be removed
# - All scheduled tasks will be removed
# Examples:
# Create and set new machine and instance IDs, in full and short forms
# change_machine_id.py --machine-id new --instance-id new
# change_machine_id.py -m new -i new
# Set predefined machine and instance IDs
# change_machine_id.py -m D2A9C54A-5D7F-4CBB-B1DB-1F2D77A012B5 -i 5449D007-3E76-47D1-9BD0-D2CBB03B775E
